Concept:Identify the correct sequence of the three words to make the sentence meaningful.
Explanation:The original sentence has (A) turning, (B) efficiency, (C) increased in that order.
The phrase "delivery efficiency in increased schedules" is awkward.
The intended meaning is "increased efficiency in delivery schedules".
To achieve this, after "delivery" we need "increased", and after "in" we need "efficiency".
Thus the correct order is: turning, increased, efficiency.
That corresponds to the arrangement ACB (A, C, B).
Answer:Option B: ACB.
